Hold your forearm up to the light and turn it over. The skin on top, the side that has faced years of West Texas sun, probably looks a little older than the skin tucked away near your inner arm. Same age, same body, two different stories. That gap is not genetics. It is the sun.
Dermatologists have a name for it: photoaging, the premature aging of skin caused by ultraviolet light. It is easy to write off fine lines and dark spots as simply getting older. But most of what we read as an aging face is really an accumulated record of sun exposure, and that distinction matters, because the sun's share is the part you can actually do something about.
How large is the sun's share? In a 2013 study of nearly 300 women published in Clinical, Cosmetic and Investigational Dermatology, researchers attributed about 80 percent of visible facial aging to sun exposure. That study looked at Caucasian skin, so the exact figure will not map onto everyone, but the direction is not in dispute: the sun does far more to how your face ages than the calendar does.
What photoaging actually is
Your skin ages along two separate tracks at once. One is intrinsic aging, the slow, genetically set change that every tissue goes through with time. You cannot negotiate with that one. The other is extrinsic aging, the wear added by things outside the body: sun, smoking, pollution, diet. Of those external factors, ultraviolet light is the heavyweight.
The visible signs pile up in familiar ways: fine lines and wrinkles, a rougher surface, loss of firmness, and uneven tone with brown spots that were not there a decade ago. None of it arrives overnight. Photoaging is cumulative, the sum of thousands of ordinary, unremarkable days outdoors.
How the sun does the damage: UVA and UVB
Ultraviolet light reaches your skin in two forms, and they do different jobs. UVA rays are the longer of the two and travel deeper into the skin, where they break down collagen and elastin, the proteins that keep skin firm and springy. According to the Skin Cancer Foundation, UVA is the ray most associated with skin aging and wrinkles, and it can pass straight through windows and cloud cover, which is why an overcast day or a long drive is not the free pass it feels like.
UVB rays are shorter and act nearer the surface. They are the ones that redden and burn you, and the Skin Cancer Foundation notes they play a key role in skin cancer. Both types damage the DNA in your skin cells.
Underneath all of it is a chemical story. UV exposure generates unstable molecules that damage cell structures, chip away at existing collagen, and slow the production of the new collagen meant to replace it. And here is the part people underestimate: you do not need a sunburn for any of this to happen. Most photoaging is absorbed quietly, in small doses, over years.
Prevention is the first and best move
Nothing you apply after the fact beats keeping the light off your skin in the first place. The federal Environmental Protection Agency notes that the sun's UV rays are strongest between 10 a.m. and 4 p.m. In Lubbock, with our high-plains elevation and long stretches of open sun, that guidance is not academic.
A few habits carry most of the weight:
- Seek shade during the middle of the day, especially when the UV index is high.
- Wear a broad-spectrum sunscreen and a wide-brimmed hat whenever you are outside for a stretch.
- Remember that UVA reaches you through glass, so the driver's-side window and the sunny desk still count.
None of this reverses damage already done. What it does is keep the next decade of it from writing itself onto your face.
What can help reverse what is already there
For photoaging you have already accumulated, the most evidence-backed topical option is a prescription retinoid: tretinoin, the active form of vitamin A. In effect, it does the reverse of what the sun does. Where UV tears collagen down, tretinoin prompts the deeper skin to build more of it. A 2022 systematic review in the International Journal of Women's Dermatology found that topical tretinoin improves the appearance of photoaged skin, and the landmark research behind it, reaching back to a 1993 New England Journal of Medicine study, showed it can partly restore collagen formation in sun-damaged skin. It also speeds up how quickly old surface cells turn over, which can smooth texture and even out tone.
Because tretinoin is a prescription and is not right for every skin or every situation, it belongs in a conversation with a physician rather than in an online cart. That is exactly the kind of thing I can walk through with you, weighing whether it fits your skin, your history, and your goals.
A topical is also not the only lever. In-office options can address the structural side of photoaging, the lost firmness and rougher texture, by prompting the skin to rebuild collagen. Sofwave, for one, uses focused ultrasound to stimulate collagen in the mid-layer of the skin; we walk through how Sofwave works in plain terms elsewhere. The broader aim, across every option, is the one behind our whole approach to regenerative aesthetics: helping you look rested and like yourself, not altered.
What this means for you
Picture someone in Lubbock in their late forties who has spent a lifetime under the West Texas sun: ballgames, afternoons at the lake, the daily commute with the sun on one arm. They are not chasing a different face. They have simply noticed that their skin looks a bit more weathered than they feel, and they want to know what is worth doing and what is just hype.
For them, the useful first step is not ordering a product online. It is sitting down with a physician who will actually look at their skin, sort the reversible from the fixed, and lay out an honest plan: what prevention still buys them, whether a prescription like tretinoin makes sense, and where an in-office treatment might fit. Because these are medical decisions, they deserve real physician oversight, not a hand-off, and they are best made inside an ongoing relationship where someone tracks your skin over time.
